Impact of non-steroidal anti-inflammatory drugs on cardiovascular risk: Is it the same in osteoarthritis and rheumatoid arthritis?

Although large-scale population studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction, this is not confirmed in patients with rheumatoid arthritis (RA). Herein, we review the litterature on the differential effects of NSAIDs on cardiovascular risk in osteoarthritis (OA) versus RA and discuss possible explanations for this discrepancy. To assess a potential additive effect of age in non-RA populations, we compared weighted mean age between RA patients and unselected NSAID users included in cohort and case–control studies that estimate the cardiovascular risk of NSAIDs, assuming that the main indication for NSAID usage in elderly populations is OA. Our hypothesis that advanced age in osteoarthtitis compared to RA patients confounds the effect of NSAIDs on cardiovasular risk was not confirmed. Several other hypotheses that can be proposed to explain this counterintuitive effect of NSAIDs on the cardiovascular risk of RA patients are discussed. We conclude that patients with RA have a lower cardiovascular disease risk associated with the use of NSAIDs, probably due to the nature of their disease per se, until further research indicates differently.     

Administration of low-molecular-weight heparin in patients with two or more unsuccessful IVF/ICSI cycles: a multicenter cohort study

To compare the effects of the administration of low-molecular-weight heparin (LMWH) in subfertile patients with two or more unsuccessful IVF/ICSI cycles. In this six-center two-arm retrospective cohort study, the study population (230 women) underwent a GnRH-antagonist protocol and was classified into two groups, according to the couse of LMWH or not. Groups were compared regarding the clinical and IVF/ICSI cycle characteristics and reproductive outcomes, whereas clinical pregnancy and miscarriage constituted the primary endpoints. Logistic regression analysis was performed to determine the potential predictors of clinical pregnancy, miscarriage and live birth rates using the Enter method. Baseline characteristics were comparable in the two groups. There was no statistically significant difference between the two study groups with regard neither to clinical pregnancy and miscarriage rates (33/133 vs. 20/97, p?=?.456 and 15/133 vs. 9/97, p?=?.624, respectively), nor to the secondary outcomes preset for this study (all p values?>.05). Logistic regression revealed that age of the woman and ICSI and dose of gonadotrophins used were predictors of clinical pregnancy and live birth, respectively. In conclusion, there is no evidence to support the standard addition of LMWH in patients with two or more unsuccessful IVF/ICSI cycles.
